ABSTRACT
Aim To explore the effect of cuminaldehyde in cumin fruit on gastric ulcer and the protective mechanism via establishing the gastric ulcer model of rats was by ethanol injury. Methods Thirty-six male R. norregicus were divided into six groups: control group, model group, omeprazole positive control group and cuminaldehyde low, medium and high dosage groups. After seven days of continuous intragastric administration, the acute gastric ulcer of R. norregicus was tested by absolute alcohol. Gastric ulcer area, inhibition rate, gastric tissue antioxidant activity, serum inflammatory factors and gastric mucosal protective factors were detected in different groups. Results The results showed that cuminaldehyde significantly reduced the area of gastric ulcer and increased the inhibition rate of gastric ulcer. The inhibition rate of cuminaldehyde at high dose group was up to 74.65%, the activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH) in gastric tissue significantly increased, and the contents of serum prolandin E
ABSTRACT
Background: Cuminum cyminum has been one of the commonly used home-based spices in India. It shows various properties such as antispasmodic, astringent, antiseptic, antioxidant, antimicrobial, analgesic, anti-inflammatory, antianxiety, anticonvulsant, and carminative. Aim and Objective: This study aimed to evaluate the antianxiety property of C. cyminum and its comparison with diazepam on albino rats. Materials and Methods: This study was conducted in Department of Pharmacology at a tertiary care center of Western Rajasthan. Adult albino rats of either sex (100–150 g) were divided into three groups. One group received distilled water and other two group received drugs – C. cyminum and Diazepam, respectively. Results: Antianxiety effect of C. cyminum was not significant in lower and medium doses (300 and 750 mg/kg). Significant antianxiety effect of C. cyminum was seen in higher dose (1000 mg/kg). Conclusion: On the basis of this study, it can be assumed that aqueous extract of C. cyminum could be a potential source to evaluate for the central nervous system disorders. Further studies are needed to explain the actual mechanism of action of C. cyminum at the cellular and molecular levels in detail.
ABSTRACT
Candida sp. especially C. albicans is the main cause of candidiasis in women in reproductive ages. The prevalence of drug resistant C. albicans along with adverse effects of current treatments have encouraged the scientists to research on medicinal plant's essential oils. The aim of this study was to evaluate the potential effects of Ziziphora tenuior, Lavandula angustifolia, Cuminum cyminum essential oils against clinical isolates of C. albicans, which were isolated from women with vulvovaginal candidiasis. The anti-candidal effects of these commercial essential oils were screened against these clinical isolates (n=80) by disc diffusion and micro-broth dilution assays. The means of inhibition zone diameters, MIC and MFCs were reported for each essential oil. Also, the capability of fungal strain for biofilm formation in comparison with C. albicans ATCC 10231 were determined. The anti-biofilm effects of essential oils against 11 biofilm producing strains of C. albicans were determined. The results showed C. cyminum and Z. tenuior essential oils had the best anti-candidal effects, while the best biofilm killing effects was for L. angustifolia essential oil. C. cyminum and Z. tenuior essential oils can be formulated for more evaluations in preclinical and clinical studies.
Candida sp., especialmente C. albicans, es la principal causa de candidiasis en mujeres en edad reproductiva. La aparición de resistencia a los antifungicos de C. albicans, junto con el riesgo de efectos adversos de los tratamientos actuales, ha llevado a los científicos a buscar alternativas en los aceites esenciales derivados de plantas. Los objetivos del estudio fueron evaluar los efectos potenciales de los aceites esenciales de Ziziphora tenuior, Lavandula angustifolia, Cuminum cyminum, contra aislados clínicos de C. albicans, obtenidos de mujeres con candidiasis vulvovaginal. Los efectos anti-Candida de estos aceites esenciales comerciales fueron probados contra estos aislados clínicos (n=80) por difusión en disco y ensayos de microdilución. Se obtuvo el promedio de diámetro de inhibición, MIC y MFCs para cada aceite esencial. También se comparó la capacidad de formación de biopelículas de 11 cepas de C. albicans de cada aislado frente a la cepa de referencia C. albicans ATCC 10231 y la capacidad de cada aceite esencial para evitar la formación de biopelículas. Los resultados muestran que los aceites esenciales de C. cyminum y Z. tenuior tuvieron la mejor actividad anti-Candida, mientras que los mejores efectos para destruir biopelículas se obtuvieron con los aceites esenciales de L. angustifolia. Los aceites esenciales de C. cyminum y Z. tenuior ameritan tener mayores evaluaciones preclínicas y clínicas.

Aim: The present study was conducted to investigate the genotoxic effect of UV-B radiation on morphological, biochemical and cytological parameters of Cuminum cyminum. Methodology: The germinated roots of cumin were exposed to UV-B radiation at different intervals viz., 20 min 40 min and 60 min, respectively, and some treated seeds were sown on pots for morphological and biochemical observation. Results: Chromosomal studies divulged that UV-B radiation has substantial impact on Active Mitotic Index (AMI %). On increasing UV-B radiation dose, the chromosomal aberration rate elevated, thus AMI % moderately decreased and Total Abnormality percentage (TAB %) gradually increased. Different types of chromosomal abnormalities were ascertained, among which scattering was more prominent. The morphological observation showed that survival percentage and plant height decreased at elevated dose of UV-B. Biochemical results indicated that chlorophyll a, chlorophyll b and carotenoid contents decreased as compared to control, but proline content showed significant increment at higher doses of UV-B.Interpretation: The observation elucidates that UV-B causes chromosomal aberrations during cell division and acts as a potent genotoxic agents for roots. Thus, it can be concluded from the above experiment that UV-B rays promote plant growth at low doses but at the higher doses, it subsequently hinders plant growth by damaging important constituents of plant cell.
ABSTRACT
Aims: We previously demonstrated that a blend of herbal extracts (Weighlevel®; a mixture of extracts from the leaves of Alchemilla vulgaris, Olea europaea, Mentha longifolia and from the seeds of Cuminum cyminum) taken 3 times per day produces weight loss in preclinical and clinical studies. The aim of the present study was to test the efficacy of a new slow-release formulation (Weighlevel® One) taken once per day on change in body weight and related measures. Study Design: Randomized, double-blind, placebo-controlled study. Place and Duration of Study: Health Clinics in Copenhagen, Denmark between 7 January 2016 and 5 March 2016. Methodology: Thirty-six adult subjects were randomized to consume the herbal blend (n = 20) or placebo (n = 16) once per day for 8 weeks. Weight and waist circumference were assessed weekly. The primary endpoint was the change from baseline in body weight for the herbal blend group compared with placebo. Secondary assessments included waist circumference, appetite, craving, bowel health, and safety and tolerability. Results: After 8 weeks, the herbal blend group lost an average of 3.7 kg (95% CI of 3.0 to 4.5 kg); whereas the placebo group lost 0.1 kg (95% CI of -0.7 to 1.0 kg). This difference in mean weight loss between the herbal blend and placebo groups was statistically significant (P <.001). A statistically significant reduction in waist circumference was also observed for the herbal blend compared with placebo (P <.001). The herbal blend was well tolerated; no adverse events were reported. Conclusion: Daily administration of this blend of herbal extracts, administered once daily, may produce weight loss.
ABSTRACT
Abstract The objective of this study was to identify the main chemical components of the essential oil of Cuminum cyminum L. (cumin) and of the fixed oils of Bertholletia excelsa (Brazil nut) and of Helianthus annuus (sunflower seed). As well as testing the three oils and three different commercial synthetic acaricides against engorged females of Rhipicephalus (Boophilus) microplus in order to explore their acaricidal efficacy. Six different concentrations of the oils (200, 100, 50, 25, 12.5 and 6.25 mg/mL) and the active principles were evaluated with the Adult Immersion Test (AIT). The two main chemicals components of C. cyminum L. were the cuminaldehyde and the γ-terpinene. In both B. excelsa and H. annuus were the linoleic and oleic acid. C. cyminum L. showed high acaricidal activity (100%) over the engorged females and on their reproductive characteristat from the concentration of 100 mg/mL. B. excelsa and H. annuus had low acaricidal activity (39.39% and 58.75% in the concentration of 200 mg/mL respectively). The amidine and the pyrethroid (35.12% and 1.50% respectively). It can be concluded that the oil of C. cyminum L. may be a phytoterapic alternative for the cattle's tick control.
Resumo O objetivo do presente estudo foi identificar os componentes químicos majoritários do óleo essencial de Cuminum cyminum L. (comino) e dos óleos fixos de Bertholletia excelsa (castanha do Brasil) e de Helianthus annuus (semente de girassol). Assim como testar os três óleos e três diferentes acaricidas comerciais sintéticos contra fêmeas ingurgitadas de Rhipicephalus (Boophilus) microplus, para explorar sua eficácia acaricida. Seis concentrações dos óleos (200, 100, 50, 25, 12,5 and 6,25 mg/mL) e os princípios ativos foram avaliados por meio do Teste de Imersão de Adultas (AIT). Os dois componentes químicos majoritários de C. cyminum L. foram o cuminaldeído e o y-terpineno. Nos óleos de B. excelsa e H. annuus os componentes majoritários foram o ácido n linoleico e oleico, respectivamente. C. cyminum L. mostrou alta atividade acaricida (100%) sobre as fêmeas ingurgitadas e suas caraterísticas reprodutivas, a partir da concentração 100 mg/mL., tornando-se uma fonte alternativa para controlar o carrapato do gado. No entanto sao necessários estudos adicionais, a serem conduzidos in vivo. B. excelsa e H. annuus tiveram baixa atividade acaricida (39,39% e 58,75% na concentração de 200 mg/mL respectivamente), não obstante apresentaram maior efeito que a amidina e o piretroide (35,12% e 1,50% respetivamente). Pode-se concluir que o óleo de C. cyminum pode ser uma alternativa fitoterápica para o controle do carrapato do gado.

ABSTRACT
The aim of the present study was to examine the antioxidant and anti-inflammatory activities of three Moroccan ethno medicinally important plants. The antioxidant activity was performed using β-Carotene bleaching assay, DPPH, ABTS and Ferric reducing assays. In vitro anti-inflammatory assays was also studied through the evaluation of membrane stabilization potential and inhibition of protein denaturation. Results revealed that Lawsonia inermis L leaves extract had significantly higher phenolics-content (5.23 g GAE/100g DW) and exhibited the highest antioxidant activity based on DPPH (IC50 = 18.26 μg/mL). The highest flavonoids content was found in Rosa damascena. L flower (3.97 RE/100g DW) which shows the highest antioxidant activity based on ABTS (30.39 mmol TE/100g DW), FRAP (38.54 mmol TE/100gDW) and β-Carotene bleaching assay (IC50 = 56.33 μg/mL). Concerning the anti-inflammatory potency, the highest membrane stabilization effect was found in Rosa damascena. L flower (IC50 = 125.02 μg/mL) and the highest anti-denaturation of protein effect was found in Lawsonia inermis L leaves extract (IC50 = 103.21 μg/mL). Consequently, to conclude flavonoids and related phenolics present in studied plant materials may possibly be responsible for the important anti-inflammatory and antioxidant activities.
ABSTRACT
Dried seeds of spices namely Brassica nigra (mustard) and Cuminum cyminum (cumin) were screened independently, in culture media, in their different forms (aqueous extracts, essential oils and powders) against some bacterial strains of spoilage and health significance. Test microorganisms included one gram+ve bacterial strain i.e. Bacillus cereus (MTCC 430) and three gram-ve bacterial strains viz. Enterococcus faecalis (MTCC 439), Psuedomonas aeruginosa (MTCC 1688) and Shigella sonnei (MTCC 2957). Spice agar method was opted for screening antibacterial activities of powdered forms of aforementioned spices at their different concentration levels (0.0, 0.1, 0.2, 0.4, 0.6, 0.8, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0 (% (w/v)). B.nigra more effectively inhibited bacterial strains in culture media. Minimum inhibitory concentrations (MIC) of powdered form of B.nigra were also determined. It was the concentration of spice which arrested the growth of bacterial strain upto 80% level of the total incubation period of 30 days. Agar-well assay was followed for antibacterial screening of aqueous extracts and essential oils of test spices. Aqueous extracts of reference spice samples did not exhibit growth inhibitory zones towards any test bacterial strains. On the other hand, essential oils of B.nigra and C.cyminum showed distinct growth inhibitory zones against all the bacterial strains under observation. Results obtained from agar well assay revealed that essential oil of B.nigra was more potent in inhibiting bacterial strains followed by C. cyminum . It was also noticed that B. cereus (gram+ve) was inhibited at lower concentrations of test substances as compared to all the other three gram-ve bacterial strains under investigation.
ABSTRACT
The goals of this study were to evaluate the effectiveness of Cuminum cyminum, Ziziphora clinopodioides and Nigella sativa essential oils to inhibit the growth of Aspergillus fumigatus and A. flavus and to evoke ultrastructural changes. The fungi were cultured into RPMI 1640 media in the presence of oils at concentrations of 8, 6, 5, 4, 3, 2, 1.5, 1.25, 1, 0.75 and 0.5 mg/ml in broth microdilution and 2, 1.5, 1 and 0.5 mg/ml in broth macrodilution methods with shaking for 48 h at 28ºC. Conidial and mycelial samples exposed to 0.25, 0.5, 1, 1.5 and 2 mg essential oils/ml for 5 days in 2 percent yeast extract granulated plus 15 percent Saccharose media were processed for transmission electron microscopy (TEM). Based on broth dilution methods, C. cyminum and to a lesser extent Z. clinopodioides oils exhibited the strongest activity against A. fumigatus and A. flavus with MIC90 ranging from 0.25 to 1.5 mg/ml, while the oil from N. sativa exhibited relatively moderate activity against two above fungi with MIC90 ranging from 1.5 to 2 mg/ml. The main changes observed by TEM were in the cell wall, plasma membrane and membranous organelles; in particular, in the nuclei and mitochondria. These modifications in fungal structure were associated with the interference of the essential oils with the enzymes responsible for cell wall synthesis, which disturbed normal growth. Moreover, the essential oils caused high vacuolation of the cytoplasm, detachment of fibrillar layer of cell wall, plasma membrane disruption and disorganization of the nuclear and mitochondrial structures. Aspergillus fumigatus and A. flavus growth inhibition induced by these oils were found to be well-correlated with subsequent morphological changes of the fungi exposed to different fungistatic concentrations of the oils. Our results show the anti-Aspergillus activities of C. cyminum, Z. clinopodioides and N. sativa essential oils, which strengthens the potential use of these substances as anti-mould in the future.
